To LEZ whom t may-concern.:

Be it known that we, CHARLES E. EARRING- ToN and JOHN G. HARRINGTON, citizens of the United States, residing at Peoria,in the county of Peoria 'and State of Illinois, have invented certain new and useful Improvements in Computing-Measures; and We do hereby declare that the following isa full, clear, and exact description of the invention, which will en- Io able others skilled in the art to which it appertains to make and use'the same.

This invention pertains to computing-measures for use in the sale of dry goods and all materials sold by lineal measurement. l

The object of the invention isto provide a. yard-measure having in connection therewith a computing-table and ravoluble chart so ar- 'ranged that at a glance a salesman may determine the price of alength of cloth instantly 2o without chance of an error, and consequently without loss either to buyer or seller. We are aware that suchdevices are not new; but those that have heretofore been brought out are inconvenient, require headwork in their use,

- and consequently are not practical.

In the accompanying drawings, Figure/1 is a plan view of the device much reduced in size. Y Fig. -1a is a perspective view of a beveled slot sho-wn in Fig. 1 with raised ribs Fig. 2 is a side view of the device in part section, showing the interior construction.V Fig. 3 is a perspective view of aportion of the device. Fig. 4 is a perspective view of another portion thereof. Fig. 5 is a cross-secgq tion. Fig. 6 is a perspective view of a coun-- ter, showing our improved device mounted thereon. andchart, showing a knob for turning it.

Fig. 8 isa plan view of a computing-chart 4o used in conjunction with the roller.

In thedrawings and specification letters of reference correspond. A indicates the body of the device, which is made, preferably, of thinmet-al, but may be`V made of wood, if desired. Thisfmerely consists, as shown in Fig. 5 in cross-section, of a substantially dat portion having a. slot B foi-,the greater portion of its length, as shown,

anda rectangular opening at one end'having f 5o beneath it a chart C,.cover ed a glass for` Fig. 7 is a side elevation of a roller,

protecting purposes. The edges of theinetal surrounding the said chart are beveled, as shown, to present a neat appearance. The said slotB is also beveled at one side, thel same being provided with a scale Arepresenting a yard divided into inches and fractions thereof, as in'common usage. Secured to the plate A on the under side are twoend hangers D D of the form shown in Fig.. 5. A roller, consisting of two end spiders or spoked wheels F, carrying a cylinder G, of light metal, is

supported between the said hangers D by means of stub-shafts H, one ofwhich carries a milled knob, by which the cylinder is revolved. Said cylinder is covered with a chart (shown in Fig, 7) and is divided into horizontal spaces. At the extreme left of these spaces are indicated cents and fractions thereof, and then carried out opposite them within the spaces are iigures, also indicating cents. The mark adjacent to each figure indicates the length of the material tobe sold. This will appear more fully hereinafter. The computing table or chart at() is arranged as shown in Fig. 8. At the extreme left is a column marked yards, bearing the numerals 1, 2, 3, 4,1. 5, and so on. (Ofthe top line are indicated the prices per yardnam-ely, c3 %,n s4 47h15, 5,1% and SO on. To ascertain the price of, say, six yards of material attive cents, we will find 3045 at the intersection of the column containing the price per yard and the line'indicating the number of yards. .The device thuscons'tructed is' attached to a counter, as indicated in Fig. 6. The counter is merely out out suliiciently to permit the article to be placed within it in such a mannerthat its rearedge is liush with the edge of the counter. Since the body A is of very thin metal, the counter'is not obstructed in any way and the inserted device is used asa portion of the counter, as isobvious. Beneath the scaled slot B is placed a strip of glass B', as shown in Fig. 5, serving to keep the cylindrical chart clean. 'Ihesaid V chart may be rotated in it's' bearing, whereby any desired horizontal column vmay be brought beneath the slot B. In order to cause the cylinder to retain anyposition at which it isset, we provide a serrated face ,at I, which IOO figure 6 at the top is reached we 'find 36 1.

at the intersection thereof, which means that six yards at six cents per yard would cost thirty-six cents. New to iind the cost of the extra one-half yard the chart on the cylinder is consulted. By turning said cylinder until the ligure (5asthe price per yardin the eX- treme left-hand column is readable beneath the slot B, as shown in Fig-1, and looking for the half-yard mark on the scale adjacent to the slot the figure 23 will b'e seen, as shown in Fig. 1, indicating three cents as the amount to charge for one-half yard of material. This is a simple calculation that can be done mentally, but for larger numbers the computation is not as easily done. Hence the chart C and cylinder are of very great advantage` resulting from the multiplication of the numbers at the head of the vertical columns and the number in the horizontal columns; but we merely place the number mentioned to carry out our idea. Let it be supposed that one dollar and twelve cents 'worth of goods is wanted at the rate ot' eight cents per yard. The dealer iinds that in the eight-cent column of the chart is found 112 opposite the number 14. Then fourteen yards is the amount of goods to be givenfor the price mentioned.

may thus quickly determine his position without having to study the scale 'particularly close.

A metal casing D is attached to the end hangers D and incloses the cylinder Gand protects it.

L lt is obvious that various sizes of our device may be ma'de and that charts or tables for high-priced goods may be used.

XVe are aware that it is not new to use charts similar to the one indicated at C; but we believe it is new to use the revoluble cylinder and scale shown in connection therewith. The loss to a dealer in a year through the carelessness of a clerk or of his inability to figure correctly is known to be considerable; but with the means for making a complete and accurate ded uction from plain figures already laid out no mistake can be made.

It is evident that the measuring-scale instead of being on the body A, as shown, may be printed 056 each horizontal line of the cylinder, so ythat it will always be in view at whatever position the said cylinder may be placed. This will simplify the construction of the device and may be usedor not, as desired. As to the charts we merely show one form of arrangement thereof; but otherforms may be employed, if desired.

1. In a computing-measure for use in selling materials by lineal measurement, the combination of the body A, a chart at one end thereof having a set of vertical columns and a set'otl horizontal columns, the former showing at the top the selling price of goods per yard, the latter indicating the number of yards to be sold, the intersections of the several columns showing the aggregate price of the number of yards at the cost given in the piiceco'lumns, a longitudinal slot B in the body between the said chart and the farther end of said body, a measuring-scale adjacent to the said slot, a revoluble cylinder beneath the slot the same having horizontal columns thereon indicating at the extreme left the prices of goods per yard, each of said columns being divided into fractions of a yard lwith the price of each fraction indicated thereon at'the rate shown in the left of each column, hangers D for supporting the said cylinder, a knob for turning the latter and a casing D surrounding it, all being arranged substantially as set forth.

2. A computing-measure for use 'in selling materials by lineal measurement having a Iiat body A, a chart attached tothe surface thereof at one end which indicates at a glance the aggregate cost of goods at the intersection of a price-per-yard column and a column showing the number of yards being sold,-in combination with a measuring-scale on the said body, a slot adjacent to the scale, a revoluble cylinder' having a chart thereon beneath the slot, said chart having horizontal columns indicated thereon on which prices per yard of goods are shown, said columns being divided into various fractions of a yard, each fraction having the price thereof indicated thereon whereby the dealer may ascertain the aggregate cost of a number of yards ata given price per yard by referring to the stationary chart and may ascertain what the fractional part of a yard would cost, at the same price, on the revoluble chart.

In a computing-measure, the combination of a body A, a chart C thereon at one end having vertical columns indicating prices of goods per yard and horizontal columns indicating numbers of yards of goods to be sold, the intersections of the columns showing the aggregate cost of yards of goods so indicated, a longitudinal slot in the body between the chart C and the opposite end of the body, a measuring-scale adjacent. to the slot, a cylindrical chart beneath the slot and readable through the latter, columns on the said cylin- IOO IIO
